Former President Joe Biden has been diagnosed with aggressive prostate cancer just months after leaving the White House. On Sunday, his office said the cancer has spread to his bones. In a statement, Biden’s office said, “While this represents a more aggressive form of the disease, the cancer appears to be hormone-sensitive which allows for effective management.” Biden is 82 years old.

The diagnosis comes amid growing scrutiny of former White House aides accused of concealing Biden’s deteriorating health in recent years. On Tuesday, CNN journalist Jake Tapper and Alex Thompson are publishing a book on the issue titled “Original Sin: President Biden’s Decline, Its Cover-Up, and His Disastrous Choice to Run Again.”
